Leonardo DiCaprio has always been popular with the pre-teen crowd, but they’re taking it a step further and giving him an award. OK, technically the award has nothing to do with his dream-boat qualities. But it has everything to do with his commitment to the environment. In recent years, DiCaprio directed and produced a documentary, The Eleventh Hour and created a foundation and website dedicated to eco issues. At the Nickelodeon Kids’ Choice Awards ceremony, to be held March 28, DiCaprio will be presented with the award by pal and fellow ecologically minded cool chick Cameron Diaz. But the question on everyone’s mind is—will he get slimed?
